[Seminar] Prof. Teppei Katori (Queen Mary University of London), Jun. 27th, 2018

We are delighted to announce that we will have Prof. Teppei Katori from Queen Mary University of London visiting SKKU and he will give a seminar on June 27th. Please join and welcome his talk together.

* Speaker:  Prof. Teppei Katori (Queen Mary University of London)
* Time: Jun. 27th (Wed.), 11am.
* Location: Seminar room, 7th floor of Samsung Library, Sungkyunkwan Univ. Natural Science Campus

* Title: Tests of Lorentz and CPT violation with neutrinos
* Abstract:

Lorentz violation has been shown to occur in Planck scale physics. Since neutrino oscillation experiments are natural interferometers, they may be sensitive to small space-time effect, such as Lorentz violation. The sensitivity is comparable to precision optical measurements (10E-19 GeV). Thus, neutrino oscillations may be the first place where we see Lorentz and CPT violation.

The LSND and MiniBooNE neutrino oscillation experiments have observed anomalous excess of electron and anti-electron neutrino events, which is consistent of neutrino oscillations through sterile neutrinos with mass around 1 eV. The search of 1eV sterile neutrino is an active field and many experiments are planned, including  JSNS2 experiment in Japan.  In this talk, I will introduce Lorentz violation and Lorentz violating neutrino oscillations. And I examine whether the MiniBooNE data may be explained through a Lorentz violation model. Then, I will discuss Lorentz violation analysis results on Double Chooz reactor oscillation experiment. Finally, I will show a future prospective of the best Lorentz violation test on the neutrino sector through the astrophysical very high-energy neutrinos at IceCube.
